Enrollment completed in Phase 3 EFZO-FIT™ study of efzofitimod in pulmonary sarcoidosis; topline data expected in the third quarter of 2025.

Publication in European Respiratory Journal demonstrated statistically significant difference in time-to-first relapse for corticosteroid use and improvement in corticosteroid relapse rate for efzofitimod.

SAN DIEGO, Nov. 07, 2024 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: ATYR) (“aTyr” or the “Company”), a clinical stage biotechnology company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase platform, today announced third quarter 2024 results and provided a corporate update.

“We achieved a significant milestone this quarter by completing enrollment in our global pivotal Phase 3 EFZO-FIT™ study in pulmonary sarcoidosis and topline data is expected in the third quarter of 2025,” said Sanjay S. Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “Additionally, our efzofitimod program was featured in this year’s Best of CHEST Journals session at the CHEST 2024 annual meeting and we recently published favorable steroid relapse data for efzofitimod in the European Respiratory Journal. These events have generated increased interest in efzofitimod and the potential promise it holds to be a transformative therapy for patients.”

Third Quarter 2024 and Subsequent Period Highlights

  • Completed enrollment in the global pivotal Phase 3 EFZO-FIT™ study to evaluate the efficacy and safety of efzofitimod in patients with pulmonary sarcoidosis. This is a randomized, double-blind, placebo-controlled, 52-week study consisting of three parallel cohorts randomized equally to either 3.0 mg/kg or 5.0 mg/kg of efzofitimod or placebo dosed intravenously monthly for a total of 12 doses. The study enrolled 268 patients with pulmonary sarcoidosis at 85 centers in nine countries, which exceeded the targeted enrollment. Topline data from the study are expected in the third quarter of 2025. Patients who complete the study and wish to receive treatment with efzofitimod outside of the clinical trial are eligible to participate in an Individual Patient Expanded Access Program (EAP).

  • Continued enrollment in the Phase 2 EFZO-CONNECT™ study to evaluate the efficacy, safety and tolerability of efzofitimod in patients with systemic sclerosis (SSc, or scleroderma)-related interstitial lung disease (SSc-ILD). This proof-of-concept study is a randomized, double-blind, placebo-controlled, 28-week study consisting of three parallel cohorts randomized 2:2:1 to either 270 mg or 450 mg of efzofitimod or placebo dosed intravenously monthly for a total of six doses. The study intends to enroll up to 25 patients with SSc-ILD and is open for enrollment at multiple centers in the United States. Patients who complete the study and wish to receive ongoing treatment with efzofitimod are eligible to participate in a 24-week open-label extension (OLE). Interim data from the study are expected in the second quarter of 2025.

  • Publication demonstrating the efficacy of efzofitimod in pulmonary sarcoidosis published in the European Respiratory Journal. Findings from a post hoc analysis of the Phase 1b/2a study of efzofitimod in patients with pulmonary sarcoidosis demonstrated a statistically significant difference in time-to-first relapse for corticosteroid use and improvement in corticosteroid relapse rate in therapeutic (3.0 and 5.0 mg/kg efzofitimod) versus subtherapeutic (1.0 mg/kg efzofitimod and placebo) groups. The publication, entitled, “Therapeutic Doses of Efzofitimod Demonstrate Efficacy in Pulmonary Sarcoidosis,” is available on the Journal’s website and can be accessed at: https://openres.ersjournals.com/content/early/2024/07/18/23120541.00536-2024.

  • Efzofitimod for pulmonary sarcoidosis featured in the Best of CHEST Journals session at the CHEST 2024 Annual Meeting. The session featured recent data and publications that generated significant interest and readership among the pulmonology community. Dr. Daniel A. Culver, Chair of the Department of Pulmonary Medicine at Cleveland Clinic, presented data from the Phase 1b/2a study published in CHEST, the post hoc analysis on corticosteroid steroid relapse published in the European Respiratory Journal with further elucidation on efzofitimod’s mechanism of action.
